Definitions
- the invention relates to a controllable gastric band having a non-extensible back and a stoma lake arranged from the back chamber for controlling the Stomaeinengung by supply and removal of liquid into and out of the chamber, wherein a second chamber is provided.
- the invention relates to a further development of the controllable gastric band, as it is offered by several companies in principle the same design (eg Sweden tape the Fa.Obtech (Johnson & Johnson), Lapband the Fa.Bioenterics, ..) This is a used for restriction of food intake band, which is wrapped around the uppermost part of the stomach or esophagus and closed.
- the WO 01/24742 A1 describes a gastric band which is wrapped around the stomach in a belt shape and attached. An adjustment of the constriction of the stoma is possible purely mechanically by narrowing the band.
- the US Pat. No. 4,592,339 A describes a gastric band in which on the stomach-facing side of the band, a chamber is arranged, which can be filled with liquid. This allows the control of the stoma size. Through a subcutaneously sewn port, which is connected via a tube with the chamber of the gastric band, a liquid filling and emptying of the system can be performed.
- the US Pat. No. 6,460,543 B1 describes a gastric band of the subject type, in which a control of stoma constriction can be made by fluid displacement, for example via a remote control. An autoregulation of stoma narrowing as a function of food intake is not provided.
- the invention aims to provide a gastric band in which a preferably automatic adjustment of the stoma width is possible. It would be desirable to have a gastric band that is tight only when eating, but the rest of the time is long enough to avoid negative consequences. The band is supposed to constrict when eating and after completing food intake, it will be wide again.
- the object of the invention is achieved on the one hand in that the second chamber is provided on the stoma side of the back, and in communication with the first chamber, so that the control of stoma narrowing is achieved by displacement of the liquid between the one chamber and the other chamber.
- regulation of gastric banding and thus stoma constriction is possible by shifting the fluid between two chambers without adding or draining the fluid to and from the outside.
- the uneven distribution of the fluid between the two chambers causes a narrower stoma in height the higher filled chamber. This creates a gastric band which has a fluid circuit.
- the object of the invention is also achieved in that the second chamber is provided on the stoma side of the back, and is designed as a sensor for detecting a pressure increase in the stomach or esophagus, and that the other chamber with a reservoir is connected, so that, depending on the pressure detected via the sensory chamber, the control of stoma constriction is achieved by displacement of the liquid between the reservoir and the stoma-constricting chamber.
- a two-cycle system is formed, wherein the sensory chamber represents a liquid space and the stoma-constricting chamber together with the reservoir represents the second liquid space.
- the chambers are preferably arranged side by side with the stoma-restricting chamber located aborally.
- the second chamber may also be divided into two communicating chambers which define the stoma-restricting chamber on both sides. This increases the stability of the gastric band.
- the chambers prefferably be arranged one above the other with respect to the stomach or esophagus, with the sensory chamber being arranged on the stomach wall.
- a layer can be arranged between the chambers.
- a device for pumping the liquid is preferably provided.
- the pump device is formed either by an electric or a mechanical driven pump, such as a suction pressure pump.
- a mechanically driven pump for example a suction pressure pump
- that energy taken up by the sensory chamber is used to inflate the ostomy constricting chamber.
- a device for detecting the food activity is advantageously provided.
- the eating activity can be done by detecting the swallowing activity, detecting the pressure on the stomach wall or esophageal wall or detecting the peristaltic wave.
- a pressure sensor may be provided in the sensory chamber, which is connected to an electronic circuit.
- the detection device is connected to the pumping device, so that after detection of the food activity, liquid is pumped from the sensory chamber or the reservoir into the stoma-restricting chamber and a certain time after detection of the termination Essensmodtician the liquid is moved back from the stoma-constricting chamber in the second chamber or the reservoir.
- the chambers are connected to each other via an auxiliary chamber with Windkesselfunktion, between the second chamber and the auxiliary chamber, a valve is arranged, which allows a liquid transport only from the second chamber to the auxiliary chamber, and between the auxiliary chamber and the stoma-constricting chamber another valve is arranged, which allows a liquid transport only from the auxiliary chamber to the stoma-constricting chamber.
- an auxiliary chamber with a wind-bowl function may also be arranged in the connection between the reservoir and the stoma-restricting chamber.
- a means for performing a fluid exchange from the stoma-constricting chamber to the second chamber or to the reservoir is provided.
- This device for carrying out the fluid exchange from the stoma-restricting chamber to the second chamber or to the reservoir can be formed by a common partition between the chambers or the chamber and the reservoir with micropores contained therein. About these micropores in the partition wall between the adjacent chambers of the gastric band or the chamber and the reservoir takes place a slow continuous fluid exchange.
- the device for carrying out a fluid exchange can also be formed by a reflux channel between the chambers or the stoma-restricting chamber and the reservoir.
- a throttle valve or the like Be arranged, which throttles the liquid flow and allows only in one direction.
- the sensory chamber is connected to a gastric pacemaker or an electrical impulse emitting device, so that, depending on the sensed in the sensory chamber pressure in the stomach or esophagus stimulation of the gastric wall by electrical impulses is achievable. This can be done during feeding a stimulation of the stomach or esophagus.
- a further fluid-filled chamber for adaptation of the gastric band may be provided, which has neither a sensory nor a stoma-constricting function within the controllable gastric band, but serves to adapt the gastric band to the respective circumstances.
- This additional chamber is placed over the sensory and stoma-constricting chamber of the gastric band and together around the uppermost part of the stomach or esophagus wrapped around and attached.
- the further chamber is connected to a port to be subcutaneously arranged, so that the chamber can be filled with liquid or fluid can be withdrawn from the chamber by supplying or discharging liquid via the port, and thus adaptation of the gastric band can take place.
- a port to be subcutaneously arranged, so that the chamber can be filled with liquid or fluid can be withdrawn from the chamber by supplying or discharging liquid via the port, and thus adaptation of the gastric band can take place.
- several such chambers may be provided for adjusting the gastric band.
- auxiliary chamber 3 With Windkesselfunktion.
- the auxiliary chamber 3 is connected to both chambers 1, 2.
- a valve 5 between the chamber 1 and the auxiliary chamber 3 allows the liquid to pass from the chamber 1 into the auxiliary chamber 3.
- Another valve 6 between the stoma-restricting chamber 2 and the auxiliary chamber 3 allows fluid to pass from the auxiliary chamber 3 into the stoma constrictor Chamber 2.
- the pressure in the two adjacent to the stomach wall 13 chambers 1, 2 thus increases from a rest pressure p1 to a pressure p2. Liquid is thus pressed from the chamber 1 into the auxiliary chamber 3.
- the valve 5 prevents a return flow from the auxiliary chamber 3 into the chamber 1. Due to the Windkessel function, the auxiliary chamber 3 stores the increased pressure p2. After passage of the bite through the stoma, the fluid pressure in the two chambers close to the stomach wall decreases again to the resting pressure p1.
- the auxiliary chamber 3 standing under the increased pressure p2 then empties the liquid into the stoma-constricting chamber 2.
- liquid from the chamber 1 enters the stoma-constricting chamber 2 postponed.
- the stoma opening is made narrower at the level of the chamber 2, as in FIG Fig. 2 shown schematically.
- the fluid displacement occurs continuously during the meal. After eating, the band is resumed after a certain time, by a reflux from the stoma-constricting chamber 2 is introduced into the chamber 1. The optimal time for this fluid exchange must be established in clinical trials.
- the aim of the autoregulatory change in stoma size is thus achieved by a fluid displacement from one chamber to the other chamber.
- amount of liquid means an unequal distribution an ostomy narrowing in the area of one and a stoma expansion at the level of the other chamber.
- the gastric ligament In effect for the gastric ligament, it means an ostomy and thus complicating the eating process.
- the in the 3 and 4 illustrated embodiments of a gastric band show variants for which two fluid circuits are provided.
- the gastric band like the bands currently used, has a non-extensible back 4.
- the chamber 1, which is arranged cranially with respect to the stomach, has the function of a sensor and detects the movements of the stomach or esophagus caused during the ingestion of food.
- the chamber 2 located next to the sensory chamber 1 serves for stoma narrowing and communicates with a reservoir 9. From this reservoir 9, liquid can be pumped into the chamber 2 and conveyed back from this into the reservoir 9.
- an electronic circuit 11 which detects the pressure absorbed by the sensory chamber 1 and controls an electric pump 12 accordingly serves for the operative connection between the chambers 1 and 2.
- the electric pump 12 conveys liquid from the reservoir 9 into the chamber 2 and thus causes a constriction of the stoma. This constriction of the stoma is thus carried out after finding the food passage through the chamber 1.
- the pressure inside the chamber 1 increases upon the passage of swallowed food, so that a controllable gastric band of conventional design can be used as a sensor for swallowing activity.
- the constriction of the stoma is effected, by repositioning the liquid in the reservoir 9, the stoma widens.
- Fig. 4 shows a variant of the controllable gastric band according to the invention in which the connection between the chamber 1 and the connected to the reservoir 9 chamber 2 via a suction pressure pump 14.
- the increasing in the sensory chamber 1 during food intake pressure for inflating the chamber 2 is used.
- the liquid in the sensory chamber 1 thus actuates the suction pressure pump 14 and causes by appropriately arranged valves 7, 8 a liquid flow from the reservoir 9 into the chamber 2 and thus causes a pumping of the chamber 2 and consequent constriction of the stoma.
- an auxiliary chamber 3 with Windkesselfunktion between the valve 8 and another valve 10
- a delayed liquid flow can take place and thus a delayed narrowing of the stoma can be achieved.
- the return flow of the liquid from the chamber 2 into the reservoir 9 can take place via a return flow channel 17 in which, for example, a throttle valve 15 can be arranged, which causes a slow dissolution of the stoma constriction.
- a throttle valve 15 can be arranged, which causes a slow dissolution of the stoma constriction.
- the embodiment according to Fig. 4 differs further from that in Fig. 3 in that the two chambers 1, 2 are arranged one above the other with respect to the stomach wall 13.
- the chambers 1, 2 are arranged radially one above the other, wherein the sensory chamber 1 is arranged on the stomach wall 13 or the esophageal wall and the chamber 2 is arranged above the chamber 1 at most with the interposition of a layer 16.
- the arrangement of the chambers 1, 2 one above the other results in a different pressure situation than in the juxtaposed chambers 1, 2.
- the superimposed chambers 1, 2 it would be in the single-circuit system according to the Fig.
- the variant with the suction pressure pump 14 according to Fig. 4 comes without electrical energy.
- the chambers 1, 2 comprise, for example, the entire circumference.
- a fluid displacement from the one chamber 1 into the stoma-restricting chamber 2 would not lead to a change in the stoma width. This is achieved only if that chamber in which the liquid is pumped, is made narrower than that chamber from which the liquid is removed. If the stoma-restricting chamber is narrower, then it is higher for the same amount of fluid and thus the stoma width is narrower. The displacement of the liquid from the wide chamber into the narrow chamber thus leads to an ostomy constriction.
- Fig. 5 shows a perspective view of another embodiment of a gastric band, wherein the sensory chamber 1 and the stoma-constricting chamber 2 are arranged side by side along the circumference of the gastric band on the non-stretchable back 4.
- the gastric band is around the wound around the upper part of the stomach or esophagus and closed.
- the two chambers 1, 2 each take only a part of the circumference.
- a further chamber 18 may be provided, which has neither a sensory nor a stoma-constricting function within the controllable gastric band, but serves to adapt the gastric band to the respective conditions.
- the elongated chamber 18 is disposed over the chambers 1, 2 of the gastric band and wrapped around the uppermost stomach part or esophagus and secured.
- the chamber 18 is connected via a corresponding line 19 in a conventional manner with a port 20 which is arranged subcutaneously.
- the adaptation of the gastric band can thus take place via supply or removal of liquid via the port 20 into or out of the chamber 18.
- Fig. 6a and 6b shows a section through such a gastric band according to Fig. 5 in the area of the stoma-restrictive chamber 2.
- the stoma-restricting chamber 2 is slightly filled so that the chamber 18 is pressed less against the stomach wall 13 (not shown) than in the situation according to FIG Fig. 6b in which the stoma-constricting chamber 2 is filled with appropriate liquid and thus the chamber 18 is pressed against the gastric band 13 or esophageal wall and there is a constriction of the stoma.
- this additional chamber 18, which does not participate in the autoregulation an optimal adaptation of the gastric band from the outside via the port 20 can thus take place.
- the sensory function of the gastric band provides a new approach to the concept of a gastric pacemaker.
- a gastric band acting as a sensor By combining a gastric band acting as a sensor with a pacemaker, the stimulation of the gastric wall by electrical Impulses are limited to the times of food intake. It would also be possible to effect activation of this sphincter muscle by appropriate placement of the pacemaker probes in the area of the lower esophageal sphincter and thus a restriction to the food passage. The restriction then causes a physiologically given structure instead of the active chamber.

Abstract
Description
Die Erfindung betrifft ein steuerbares Magenband mit einem nicht dehnbaren Rücken und einer stomaseitig vom Rücken angeordneten Kammer zur Steuerung der Stomaeinengung durch Zu- bzw. Abfuhr von Flüssigkeit in die bzw. aus der Kammer, wobei eine zweite Kammer vorgesehen ist.The invention relates to a controllable gastric band having a non-extensible back and a stomaseitig arranged from the back chamber for controlling the Stomaeinengung by supply and removal of liquid into and out of the chamber, wherein a second chamber is provided.
Die Erfindung bezieht sich auf eine Weiterentwicklung des steuerbaren Magenbandes, wie es von mehreren Firmen in prinzipiell gleicher Bauform angeboten wird (z.B. Schwedenband der Fa.Obtech (Johnson & Johnson), Lapband der Fa.Bioenterics,..) Es handelt sich hierbei um ein zur Restriktion der Nahrungsaufnahme eingesetztes Band, das um den obersten Magenteil bzw. Ösophagus herumgeschlungen und verschlossen wird.The invention relates to a further development of the controllable gastric band, as it is offered by several companies in principle the same design (eg Sweden tape the Fa.Obtech (Johnson & Johnson), Lapband the Fa.Bioenterics, ..) This is a used for restriction of food intake band, which is wrapped around the uppermost part of the stomach or esophagus and closed.

Die derzeit verwendeten Magenbänder bringen in der Mehrzahl der Fälle sehr gute Langzeitergebnisse hinsichtlich Gewichtsreduktion und Patientenzufriedenheit. Dennoch gibt es einige Probleme die besonders bei hoher Bandauffüllung in den Vordergrund treten. Viele Patienten berichten dann über die unangenehme Erscheinung des Speichel-Erbrechens bzw. Herauswürgens, v.a. beim flachen Liegen. Speisereste können lange oberhalb des Stomas in der Speiseröhre verbleiben, hier zu gären beginnen und dadurch neben einem unangenehmen Mundgeruch eine Schleimhautreizung mit entsprechenden Schmerzen hervorrufen. Die ununterbrochen bestehende hohe Engstellung des Stomas führt wie bei einer Achalasie im Verlauf von Monaten zu einer zunehmenden Ausdehnung der Speiseröhre, wodurch schließlich die Ösophagus-Sensibilität schwindet und die Bandwirkung verloren geht, was dann zu einer Gewichtszunahme trotz liegendem hoch aufgefülltem Magenband führt.The currently used gastric bands bring in the majority of Cases very good long-term results in terms of weight loss and patient satisfaction. Nevertheless, there are some problems that come in the foreground especially with high volume replenishment. Many patients then report the unpleasant phenomenon of saliva vomiting or choking, especially when lying flat. Food debris can remain in the esophagus for a long time above the stoma, begin to ferment here, and in addition to an unpleasant halitosis, cause mucous membrane irritation with corresponding pain. As with achalasia, the uninterrupted high stenosis of the stoma leads to increased esophageal dilatation over the course of months, eventually causing esophageal sensibility to diminish and loss of ligamentous effect, leading to weight gain despite the presence of a highly inflated gastric band.
Das Problem bei derzeit verwendeten Magenbändern besteht darin, dass die gewählte Auffüllung und damit Stomaweite ständig gleich bleibt, obwohl nur eine Restriktion der Nahrungsaufnahme angestrebt wird.The problem with currently used gastric bands is that the chosen filling and thus stoma size remains constant, although only a restriction of food intake is sought.
Ausgehend von dem Stand der Technik beim derzeit verwendeten Magenband zielt die Erfindung darauf ab, ein Magenband zu schaffen, bei dem eine vorzugsweise automatische Einstellung der Stomaweite möglich ist. Anzustreben wäre ein Magenband, das nur bei der Nahrungsaufnahme eng gestellt ist, die übrige Zeit aber ausreichend weit ist, um keine negativen Folgewirkungen zu erzeugen. Das Band soll sich beim Essen einengen und nach Abschluss der Nahrungsaufnahme wieder weit werden.Starting from the state of the art in the presently used gastric band, the invention aims to provide a gastric band in which a preferably automatic adjustment of the stoma width is possible. It would be desirable to have a gastric band that is tight only when eating, but the rest of the time is long enough to avoid negative consequences. The band is supposed to constrict when eating and after completing food intake, it will be wide again.
Gelöst wird die erfindungsgemäße Aufgabe einerseits dadurch, dass die zweite Kammer stomaseitig vom Rücken vorgesehen ist, und mit der ersten Kammer in Verbindung steht, so dass die Steuerung der Stomaeinengung durch Verschiebung der Flüssigkeit zwischen der einen Kammer und der anderen Kammer erreicht wird. Somit ist eine Regulation des Magenbandes und somit der Stomaeinengung durch Verschiebung der Flüssigkeit zwischen zwei Kammern ohne das Hinzufügen oder Ableiten der Flüssigkeit von bzw. nach außen möglich. Die Ungleichverteilung der Flüssigkeit zwischen den beiden Kammern bewirkt ein engeres Stoma in Höhe der höher aufgefüllten Kammer. Dadurch wird ein Magenband geschaffen, welches einen Flüssigkeitskreislauf aufweist.The object of the invention is achieved on the one hand in that the second chamber is provided on the stoma side of the back, and in communication with the first chamber, so that the control of stoma narrowing is achieved by displacement of the liquid between the one chamber and the other chamber. Thus, regulation of gastric banding and thus stoma constriction is possible by shifting the fluid between two chambers without adding or draining the fluid to and from the outside. The uneven distribution of the fluid between the two chambers causes a narrower stoma in height the higher filled chamber. This creates a gastric band which has a fluid circuit.
Gelöst wird die erfindungsgemäße Aufgabe auch dadurch, dass die zweite Kammer stomaseitig vom Rücken vorgesehen ist, und als Sensor zur Erfassung eines Druckanstiegs im Magen bzw. Ösophagus ausgebildet ist, und dass die andere Kammer mit einem Reservoir verbunden ist, so dass in Abhängigkeit des über die sensorische Kammer erfassten Drucks die Steuerung der Stomaeinengung durch Verschiebung der Flüssigkeit zwischen dem Reservoir und der Stoma-einengenden Kammer erreicht wird. Durch diese Ausführungsform wird ein Zwei-Kreislauf-System gebildet, wobei die sensorische Kammer einen Flüssigkeitsraum darstellt und die Stoma-einengende Kammer zusammen mit dem Reservoir den zweiten Flüssigkeitsraum darstellt. Somit kommt es nicht, wie beim Ein-Kammerkreislauf-System zu einer Flüssigkeitsverschiebung von der einen Kammer zur anderen Kammer, sondern in Abhängigkeit des über die sensorische Kammer erfassten Drucks zu einer Verschiebung der Flüssigkeit vom Reservoir zur Stoma-einengenden Kammer und umgekehrt. Die beiden Kammern stehen somit in Wirkverbindung miteinander.The object of the invention is also achieved in that the second chamber is provided on the stoma side of the back, and is designed as a sensor for detecting a pressure increase in the stomach or esophagus, and that the other chamber with a reservoir is connected, so that, depending on the pressure detected via the sensory chamber, the control of stoma constriction is achieved by displacement of the liquid between the reservoir and the stoma-constricting chamber. By this embodiment, a two-cycle system is formed, wherein the sensory chamber represents a liquid space and the stoma-constricting chamber together with the reservoir represents the second liquid space. Thus, as in the single-chamber circulatory system, there is no fluid displacement from one chamber to the other, but, depending on the pressure detected across the sensory chamber, a displacement of fluid from the reservoir to the stoma-obstructing chamber and vice versa. The two chambers are thus in operative connection with each other.
Die Kammern sind vorzugsweise nebeneinander angeordnet, wobei die Stoma-einengende Kammer aboral gelegen ist.The chambers are preferably arranged side by side with the stoma-restricting chamber located aborally.
Die zweite Kammer kann auch in zwei kommunizierende Kammern unterteilt sein, welche die Stoma-einengende Kammer an beiden Seiten begrenzen. Dadurch wird die Stabilität des Magenbandes erhöht.The second chamber may also be divided into two communicating chambers which define the stoma-restricting chamber on both sides. This increases the stability of the gastric band.
Ebenso ist es möglich, dass die Kammern in Bezug auf den Magen bzw. Ösophagus übereinander angeordnet sind, wobei die sensorische Kammer an der Magenwand angeordnet ist.It is also possible for the chambers to be arranged one above the other with respect to the stomach or esophagus, with the sensory chamber being arranged on the stomach wall.
Dabei kann zwischen den Kammern eine Schicht angeordnet sein.In this case, a layer can be arranged between the chambers.
Zum Verschieben der Flüssigkeit von einer Kammer bzw. dem Reservoir in die Stoma-einengende Kammer und umgekehrt ist vorzugsweise eine Einrichtung zum Pumpen der Flüssigkeit vorgesehen.To move the liquid from a chamber or the reservoir into the stoma-constricting chamber and vice versa, a device for pumping the liquid is preferably provided.
Dabei ist die Pumpeinrichtung entweder durch eine elektrische oder eine mechanische angetriebene Pumpe, beispielsweise eine Saugdruckpumpe gebildet. Im Fall der Verwendung einer mechanisch angetriebenen Pumpe, beispielsweise einer Saugdruckpumpe wird jene Energie, welche von der sensorischen Kammer aufgenommen wird zum Aufpumpen der Stoma-einengenden Kammer verwendet.In this case, the pump device is formed either by an electric or a mechanical driven pump, such as a suction pressure pump. In the case of using a mechanically driven pump, for example a suction pressure pump, that energy taken up by the sensory chamber is used to inflate the ostomy constricting chamber.
Zur Erzielung einer Autoregulation der Stomaeinengung durch das Magenband ist vorteilhafterweise eine Einrichtung zur Erfassung der Essensaktivität vorgesehen.To achieve autoregulation of the stoma narrowing through the gastric band, a device for detecting the food activity is advantageously provided.
Dabei kann die Essensaktivität durch Erfassung der Schluckaktivität, Erfassung des Druckes an der Magenwand bzw. Ösophaguswand oder Erfassung der peristaltischen Welle geschehen. Zur Erfassung des Druckes an der Magenwand bzw. Ösophaguswand kann in der sensorischen Kammer ein Drucksensor vorgesehen sein, welcher mit einer elektronischen Schaltung verbunden ist.The eating activity can be done by detecting the swallowing activity, detecting the pressure on the stomach wall or esophageal wall or detecting the peristaltic wave. For detecting the pressure on the stomach wall or esophageal wall, a pressure sensor may be provided in the sensory chamber, which is connected to an electronic circuit.
Gemäß einem weiteren Merkmal der Erfindung ist vorgesehen, dass die Erfassungseinrichtung mit der Pumpeinrichtung verbunden ist, so dass nach Erfassung der Essensaktivität Flüssigkeit von der sensorischen Kammer bzw. dem Reservoir in die Stoma-einengende Kammer gepumpt wird und eine bestimmte Zeit nach Erfassung der Beendigung der Essensaktivität die Flüssigkeit wieder von der Stoma-einengenden Kammer in die zweite Kammer bzw. das Reservoir zurückbewegt wird. Dadurch kann eine automatische Stomaeinengung in Abhängigkeit der Nahrungsaufnahme stattfinden.According to a further feature of the invention it is provided that the detection device is connected to the pumping device, so that after detection of the food activity, liquid is pumped from the sensory chamber or the reservoir into the stoma-restricting chamber and a certain time after detection of the termination Essensaktivität the liquid is moved back from the stoma-constricting chamber in the second chamber or the reservoir. As a result, an automatic stoma narrowing depending on the food intake take place.
Gemäß einer Ausführungsvariante eines Magenbandes mit nur einem Flüssigkeitskreislauf auf rein mechanischem Wege sind die Kammern über eine Hilfskammer mit Windkesselfunktion miteinander verbunden, wobei zwischen der zweiten Kammer und der Hilfskammer ein Ventil angeordnet ist, welches einen Flüssigkeitstransport nur von der zweiten Kammer zur Hilfskammer zulässt, und zwischen der Hilfskammer und der Stoma-einengenden Kammer ein weiteres Ventil angeordnet ist, welches einen Flüssigkeitstransport nur von der Hilfskammer zur Stoma-einengenden Kammer zulässt.According to an embodiment of a gastric band having only one fluid circuit in a purely mechanical way, the chambers are connected to each other via an auxiliary chamber with Windkesselfunktion, between the second chamber and the auxiliary chamber, a valve is arranged, which allows a liquid transport only from the second chamber to the auxiliary chamber, and between the auxiliary chamber and the stoma-constricting chamber another valve is arranged, which allows a liquid transport only from the auxiliary chamber to the stoma-constricting chamber.
Im Fall eines Magenbandes mit zwei Flüssigkeitskreisläufen kann in der Verbindung zwischen dem Reservoir und der Stoma-einengenden Kammer ebenfalls eine Hilfskammer mit Windkesselfunktion angeordnet sein. Dadurch kann die durch den Druckanstieg im Magen bzw. Ösophagus auftretende Energie kurzzeitig zwischengespeichert und erst dann zum Aufpumpen der Stoma-einengenden Kammer verwendet werden. Dadurch wir erreicht, dass erst nach Abklingen der peristaltischen Welle die Stoma-einengende Kammer aktiviert wird.In the case of a gastric band having two fluid circuits, an auxiliary chamber with a wind-bowl function may also be arranged in the connection between the reservoir and the stoma-restricting chamber. As a result, the energy occurring due to the increase in pressure in the stomach or esophagus can be stored temporarily for a short time and only then used to inflate the stoma-restricting chamber. Thus we achieved that only after the subsidence of the peristaltic wave the stoma restricting Chamber is activated.
Um einen Flüssigkeitsaustausch zwischen der Stoma-einengenden Kammer und der zweiten Kammer bzw. dem Reservoir zu gewährleisten, ist eine Einrichtung zur Durchführung eines Flüssigkeitsaustauschs von der Stoma-einengenden Kammer zur zweiten Kammer bzw. zum Reservoir vorgesehen.In order to ensure a fluid exchange between the stoma-constricting chamber and the second chamber or the reservoir, a means for performing a fluid exchange from the stoma-constricting chamber to the second chamber or to the reservoir is provided.
Diese Einrichtung zur Durchführung des Flüssigkeitsaustausches von der Stoma-einengenden Kammer zur zweiten Kammer bzw. zum Reservoir kann durch eine gemeinsame Trennwand zwischen den Kammern bzw. der Kammer und dem Reservoir mit darin enthaltenen Mikroporen gebildet sein. Über diese Mikroporen in der Trennwand zwischen den aneinander angrenzenden Kammern des Magenbandes bzw. der Kammer und dem Reservoir findet ein langsamer kontinuierlicher Flüssigkeitsaustausch statt.This device for carrying out the fluid exchange from the stoma-restricting chamber to the second chamber or to the reservoir can be formed by a common partition between the chambers or the chamber and the reservoir with micropores contained therein. About these micropores in the partition wall between the adjacent chambers of the gastric band or the chamber and the reservoir takes place a slow continuous fluid exchange.
Die Einrichtung zur Durchführung eines Flüssigkeitsaustauschs kann auch durch einen Rückflusskanal zwischen den Kammern bzw. der Stoma-einengenden Kammer und dem Reservoir gebildet sein.The device for carrying out a fluid exchange can also be formed by a reflux channel between the chambers or the stoma-restricting chamber and the reservoir.
Darin kann ein Drosselventil oder dgl. angeordnet sein, welches den Flüssigkeitsstrom drosselt und nur in eine Richtung zuläßt.Therein, a throttle valve or the like. Be arranged, which throttles the liquid flow and allows only in one direction.
Gemäß einem weiteren Merkmal der Erfindung ist es vorgesehen, dass die sensorische Kammer mit einem Magenschrittmacher oder einem elektrische Impulse abgebenden Gerät in Verbindung steht, so dass in Abhängigkeit des in der sensorischen Kammer erfassten Drucks im Magen bzw. Ösophagus eine Stimulierung der Magenwand durch elektrische Impulse erzielbar ist. Dadurch kann während der Nahrungsaufnahme eine Stimulierung des Magens oder des Ösophagus durchgeführt werden.According to a further feature of the invention, it is provided that the sensory chamber is connected to a gastric pacemaker or an electrical impulse emitting device, so that, depending on the sensed in the sensory chamber pressure in the stomach or esophagus stimulation of the gastric wall by electrical impulses is achievable. This can be done during feeding a stimulation of the stomach or esophagus.
Zusätzlich kann eine weitere flüssigkeitsgefüllte Kammer zur Anpassung des Magenbandes vorgesehen sein, welche weder eine sensorische noch eine Stoma-einengende Funktion im Rahmen des steuerbaren Magenbandes aufweist, sondern zur Anpassung des Magenbandes an die jeweiligen Gegebenheiten dient. Diese weitere Kammer wird über der sensorischen und Stoma-einengenden Kammer des Magenbandes angeordnet und zusammen um den obersten Magenteil bzw. Ösophagus herumgeschlungen und befestigt.In addition, a further fluid-filled chamber for adaptation of the gastric band may be provided, which has neither a sensory nor a stoma-constricting function within the controllable gastric band, but serves to adapt the gastric band to the respective circumstances. This additional chamber is placed over the sensory and stoma-constricting chamber of the gastric band and together around the uppermost part of the stomach or esophagus wrapped around and attached.
Vorteilhafterweise ist die weitere Kammer mit einem subkutan anzuordnenden Port verbunden, so dass durch Zuführung bzw. Abführung von Flüssigkeit über den Port die Kammer mit Flüssigkeit befüllt bzw. der Kammer Flüssigkeit entzogen werden kann und so eine Anpassung des Magenbandes erfolgen kann. Natürlich können auch mehrere solche Kammern zur Anpassung des Magenbandes vorgesehen sein.Advantageously, the further chamber is connected to a port to be subcutaneously arranged, so that the chamber can be filled with liquid or fluid can be withdrawn from the chamber by supplying or discharging liquid via the port, and thus adaptation of the gastric band can take place. Of course, several such chambers may be provided for adjusting the gastric band.

Das Ziel der autoregulatorischen Veränderung der Stomaweite wird somit durch eine Flüssigkeitsverschiebung von einer Kammer in die andere Kammer erreicht. Gegenüber dem Ausgangszustand der in beiden Kammern gleichverteilten Flüssigkeitsmenge bedeutet eine Ungleichverteilung eine Stomaeinengung im Bereich der einen und eine Stomaerweitung in Höhe der anderen Kammer. Im Effekt für den Magenbandträger bedeutet es eine Stomaeinengung und damit Erschwerung des Essvorganges.The aim of the autoregulatory change in stoma size is thus achieved by a fluid displacement from one chamber to the other chamber. Compared to the initial state of the equally distributed in both chambers amount of liquid means an unequal distribution an ostomy narrowing in the area of one and a stoma expansion at the level of the other chamber. In effect for the gastric ligament, it means an ostomy and thus complicating the eating process.

Die sensorische Funktion des Magenbandes ermöglicht einen neuen Zugang zum Konzept eines Magenschrittmachers. Durch die Kombination eines als Sensor arbeitenden Magenbandes mit einem Schrittmacher kann die Stimulierung der Magenwand durch elektrische Impulse auf die Zeiten der Nahrungsaufnahme beschränkt werden. Auch wäre es möglich durch entsprechende Platzierung der Schrittmachersonden im Bereich des unteren Ösophagussphinkter eine Aktivierung dieses Schließmuskels zu bewirken und damit eine Restriktion auf die Nahrungspassage. Die Restriktion bewirkt dann statt der aktiven Kammer eine physiologisch gegebene Struktur.The sensory function of the gastric band provides a new approach to the concept of a gastric pacemaker. By combining a gastric band acting as a sensor with a pacemaker, the stimulation of the gastric wall by electrical Impulses are limited to the times of food intake. It would also be possible to effect activation of this sphincter muscle by appropriate placement of the pacemaker probes in the area of the lower esophageal sphincter and thus a restriction to the food passage. The restriction then causes a physiologically given structure instead of the active chamber.
